# Get Started With Autotune

## How to set up Autotune

1. To create a new Autotune experiment, navigate to the [Autotune section on the Statsig console](https://console.statsig.com/autotune).
2. Click **Create** and enter the name and description for the Autotune experiment.
3. Provide the variants to test in the Autotune experiment. Each variant needs a name, and a corresponding JSON value. Statsig returns the variant listed as Control/Default when the Autotune experiment isn't running.

4. Select the success event to optimize for. You can further specify an optional [event value](https://docs.statsig.com/guides/logging-events).

You can specify a few parameters:

| Parameter | Description |
| --- | --- |
| Exploration Window | The initial time period where Autotune equally splits traffic. This is useful for noisy or temporal metrics where hourly data swings can bias Autotune's initial measurements. |
| Attribution Window | The maximum duration between the exposure and success event that counts as a success. Statsig recommends 1 hour for most applications; adjust if you expect the success event to lag the exposure event by several hours. |
| Winner Threshold | The "probability of best" threshold a variant must reach for Autotune to declare it the winner, stop collecting data, and direct all traffic. A lower value results in faster decisions but increases the probability of selecting the wrong winner. |

Click **Create** to finalize the setup.

6. As with Feature Gates and Experiments, Statsig provides a code snippet for the exposure check event to add to your code. Select **Start** when you're ready to launch your Autotune test.

## Schedule the start time

Instead of launching an Autotune right away, you can schedule it to start at a specific time. This is useful when you want a test to begin during a particular window, such as after a holiday, without having to start it manually.

To schedule the start:

1. Select **Start** to open the start dialog.
2. Turn on **Schedule Autotune Start Time**.
3. Choose the date and time you want the Autotune to begin. You can schedule a start up to one year in advance, and times snap to the nearest 15-minute interval. The picker uses your local time zone.
4. Select **Schedule Start**.

The Autotune shows a Scheduled status until the start time, when it launches automatically. To change or remove a scheduled start before it begins, use the **Edit Scheduled Start** or **Cancel Scheduled Start** option on the Autotune.
